Assembly and Operation
STEP 1 - Set up the supports
To assemble the model, begin by setting up the aluminum supports. The shorter support will
hold the downstream end of the box, so keep in mind how you would like the model oriented
when placing the supports.
If the supports are not properly aligned, the box will twist when fully loaded, which may
damage the box. To check alignment, look across the support crossbars as shown in
Figure 3. The supports must be both level and parallel.
The supports should be set up so that the crossbars are 49 in (1.25 m) apart and aligned as
shown in Figure 3 to prevent damage to the box.

parallel when viewed as shown.
WARNING
When fully charged with water, the model can weigh in excess of 500 lb (227 kg). Dynamic loading during
use, caused by someone leaning on the model, for example, can greatly increase this load. A collapse of
the model’s supports could be dangerous and seriously damage the model. You must be certain the
model is adequately supported and that you have read and understand all warnings.
